Let's Talk About Love by Claire Kann
Alice is generally pretty happy. She has two best friends who are about to get married, a summer job at her local library, an undeclared college major, and a supportive if overbearing and judgmental family. But things get shaken up when she gets a new coworker, Takumi, who she is instantly attracted to. He's off-the-charts cute, smart, sweet, and funny, and he seems to like her back. There's just one problem-- Alice is asexual, and her previous attempts at relationships have all gone... badly.
